Just looking at the temperature range on Mars. It's 1.5x the distance from the sun as earth and the surface temp ranges from a balmy 70F to -225F.
Elon specifically has this dream of colonizing mars, but it seems unrealistic. Perhaps in the future there could be an outpost where humans can visit for extended periods of time, but living there forever seems kind of sucky.
Ya have you seen a red spherical rock roughly the size and distance that Nasa claims? What details do you see?
I also don't know the size, distance, or texture, but yes I've seen a reddish sphere in the sky
